I really, really, really wish I could rate it higher. Prior to November/October this would easily be a 4 or 5 star rating. Since then, however, there's been noticeable slowing in my system to the point that I can't use FF while this extension is enabled. I don't know if this add-on changed or if FF did, but I went from using this extension 24/7 to only using it when my eyes are really hurting and, even then, while needing to weigh out what speed I need pages to work at. The extension has crashed my browser multiple times and has been a disappointment since. I'll amend this if it's fixed, but for now I can't recommend this extension :(

Super schön, aber sehr Ressourcen-hungrig. Habe mich für eine andere Dark Erweiterung von Mikhail Khvoinitsky entschieden, die genauso 1A funktioniert. Die hat zwar nicht soviel Einstellmöglichkeiten, sie ist nicht sonderlich aktuell, aber die Webseiten sehen alle identisch dunkel aus (im Vergleich zur dieser hier) und ich habe weniger Ressourcenverbrauch.

Stopped working as of 29 Dec 25. Stays on dark mode even during daytime hours. Will revisit later and revise review accordingly

I installed this add-on because it was a "recommended" extension. I've been using this DR for several months. Today, strangely, it stopped working. I closed and restarted Firefox and DR was gone. It simply disappeared from my list of installed add-ons. Why would it do this?

Great

this is not the extension some people are complaining about being a malware.

its the fake version called "dark reader for ff" pretending to be this extension and other 17 extensions.

dnt listen to crybabies. confirm the news before removing a good extension like DR

here is the list of all the extensions directly copied from KOI's website. the one who broke this news

This addon is NOT the addon mentioned in recent articles (December 15th 2025'ish). Google "dark reader github" Then click the discussion tab at the top. A Dark Reader Dev has posted that this is NOT the addon mentioned in the news, regarding stenography malware.

Been using this for years, highly recommend, saves my eyes and keeps my OLED screens dark for long term survivability.

N'est pas gratuit. Il faut payer pour l'utiliser. Ceci n'est pas mentionné sur la page de l'extension.

great for making everything comic sans

Darkmoding is a lifestyle.

For me, it only works on the tabs pane, sites remans the same

I like this addon, but I really want an option to use it on restricted websites.

Its a good addon, but it automatically turns my custom theme black, which is why i did not rate it 5 stars.

If the option to leave the theme alone appears, ill fix this rating to a 5, but otherwise, it gets a 4.

Let me have my stary pixelated theme god damn it >:T

life-saver for my retinas, HOWEVER
costs a LOT of ram. if your browser lags hard i gotta go to task manager, firefox and kill the sub-program trying to eat 12gb of my 32 ram. usually works for long enough until i gotta repeat 10-15 mins later

Works well on most websites, with or without tweaking. Prevents flashbangs even on "dark-themed" sites.
